DOI: 10.1016/j.cja.2019.12.001
Abstract: Abstract Widespread usage of bump-type foil journal bearing (BFJB) in oil-free micro-turbomachinery requires accurate predictions of dynamic performance characteristics, although it remains a challenging issue because BFJB reflects nonlinear both structurally and aerodynamically. This paper… read more here.

DOI: 10.1016/j.concog.2019.102876
Abstract: The reminiscence bump is the disproportionally high reporting of autobiographical memories from adolescence and early adulthood and is typically observed when memories are evoked by cues, such as words, pictures, and sounds. However, when odors… read more here.

DOI: 10.1017/jfm.2017.41
Abstract: Geophysical granular flows, such as avalanches, debris flows, lahars and pyroclastic flows, are always strongly influenced by the basal topography that they flow over. In particular, localised bumps or obstacles can generate rapid changes in… read more here.

DOI: 10.1093/mnras/staa176
Abstract: The evolution of low-mass stars into red giants is still poorly understood. During this evolution the core of the star contracts and, simultaneously, the envelope expands -- a process known as the `mirror'. Additionally, there… read more here.
